The main feature of helmet is head protection capability in case of an accident. To determine the strength of the helmet, it is necessary to conduct tests, applying the breaking loads. Each motorcycle helmet consists of two main parts: a hard shell and a damping layer. The shell of the Predator helmet made of several layers of fiberglass and Kevlar; this technology is so far the best in the production of high quality and reliable helmets. Compromise solution, which is often used in the production of inexpensive helmets, is the production of polycarbonate. In this video, you’ll clearly see the damages of the shells of standard polycarbonate and composite helmets in comparison with Predator helmet shell.
